DS sneaker is true to size, in additon, you can use the size chart of DS (JP size) and minus 1 cm, this is the length of your foot, for ex, if my foot is 27cm => choose size indicate 28cm in JP size in the size chart ( size 10US)

Ok, my bad...should have asked the straight way in the first place Say...if i want a pair of flip-flops, and they doesn`t have my size, could i size down considering there`s no front enclosure so they won`t be tight on the toes like a normal shoe? Sure it`s a good thing to not get the toes walking themselves on the pavement
